Combined Analysis
NMMA is capable of performing combined analyses to constrain:
- the neutron star equation of state (EOS), and
- the Hubble Constant.
In the following, we will take as an example the EOS analysis.
EOS analysis
Generate a simulation set First of all, you need to create an output directory, this output will host all the data that will be used to constrain the EOS.
mkdir -p ./output
Running the following command line will generate a json file (injection.json) with the BILBY processing of compact binary merging events. We take here binaries of type BNS (NSBH is also an option). This injection comprises a simulation set of parameters: luminosity_distance, log10_mej_wind, KNphi, inclination_EM, KNtimeshift, geocent_time for the Bu2019lm model. This creates an injection.json file in the ./output directory.
nmma_create_injection --prior-file ./priors/Bu2019lm.prior --eos-file ./example_files/eos/ALF2.dat --binary-type BNS -f ./output/injection --n-injection 100 --original-parameters --extension json
